Specification forming part of Letters Patent N0."lfi3zs70 dated August4, 1874 vapplication tiled f'July127 1874.

To all whom it may concern:

Be it known that I, JONATHAN R. WEBBER, of Sedalia, in the county ofPettis and State of Missouri, have invented certain new and usefulImprovements in Heating Attachment for Stove-Pipes, of which thefollowing is a specification This invention relates to that class ofdevices in which a supplementary pipe is located within the stove-pipeproper, and communicates with the external atmosphere at both of itsends'in such a manner that air entering the lower end of said pipepasses up the same and escapes at its upper end, being heated in itspassage by the products of combustion passing from the stove up thestovepipe, so that said supplementary pipe assists in heating anapartment without an increase in the amount of fuel used.

The object of this invention is to furnish a heating attachment whichcan be readily applied to the stove-pipes now in use with but a slightalteration in their construction, and with little expense; and theinvention consists of a cylindrical pipe, having at each end detach ableT-shaped pipes or connections, which are arranged in a stove-pipe, so asto communicate with the external air at the top and bottom of said pipe,whereby air is admitted to the heating-chamber through the T-shapedlower end of said chamber, and is heated by the products of combustionpassin g up through the stove-pipe, which heated air escapes'into theroom at the upper end of the heat-generator, and aids in heating theroom, greatly increasing the heating capacity of a stove without anincreasein the amount of fuel used.

In the drawings, Figure 1 represents a vertical section of thestove-pipe having my improved heating attachment applied thereto; Fig.2, a side elevation of the same; and Fig. 3, a detached view of theheating attachment; and Fig. 4, a transverse section.

The letter A represents a hollow cylinder, and B B the detachableT-shaped end connections, which consist of a vertical portion, a, andlateral arms or pipes b b, the outer ends of the latter being providedwith flanges c c. 0 represents the section of a stove-pipe, each end ofwhich is slightly smaller in diameter than its body to receive the endsof the sections of pipe D D, and each end of the section (J is providedwith elongated slots d d rounded or curved at their upper sides. Thearms b of the end connections B are placed in the slots d of the sectionG at each end of the same, and, i being of a circular form, fit in therounded upper portions of the slots, and their flanges c overlap theedges of the slots and retain the arms b firmly in place. Thecylindrical pipe A is arranged within the section 0 with its ends in thevertical arms a of the end connections or T-shaped pipes B, the diameterof the pipeA being such as to create a space between it and thestove-pipe section 0, to permit the upward passage of the products ofcombustion. The ends of the sections D D are also provided with slots d,so that when passed onto the ends of the pipe 0 the space of the slotsat not occupied by the arms b will be covered, and thus produce a tightjoint.

The connections or T-shaped pipes B may be made of cast metal for largestoves, drums, or furnaces, or, for small stoves, may be struck up fromsheet metal, which is easily accomplished, as they are made separatefrom the cylinder A.

The operation is as follows: The cold air entering the arms b at thelower end of the cylinder A is heated by the products of combustionpassing up the stove-pipe from the stove or furnace, and the heated airescapes through the arms b at the upper end of the cylinder A into theroom, thus serving to assist in warming the same, and creating acontinuous circulation of air through the heating attachment, by whichmeans the heating capacity of the stove is greatly increased withoutrequiring an increase in the amount of fuel necessary.

A heating attachment constructed as above described can be applied toany of the stovepipes now in use by merely providing the ends of thesections with slots 66, as described, for the reception of the arms b,and by this means there is but little expense and trouble incurred inapplying the same, and, further, during the heated term of the year,where the stove is employed for cooking purposes, and it is not requiredto heat the room to any extent, the heating attachment may be removed,and the sections of the pipe applied to each other so that the slots towill be out of coincidence, and,

when required, the heating attachment may be as easily applied, asbefore described.

In some instances I make the cylinder A of such length that the upperT-shaped connection extends into the upper room, and thus utilize theheat passing up the chimney from the stove to heat such room, and byadding another heating attachment two or more upper rooms may be heatedin a like manner without increasing the quantity of fuel used.

If desired, a damper, as shown in dotted lines, Fig. 1, of the drawings,may be located within the vertical arm a of the detachable top sectionB, in order to regulate the heating capacity of the attachment.

, Having thus fully described my invention,

what I claim as new, and desire to secure-b Letters Patent, is-- v Aheating attachment for stove-pipes, con sisting of the detachablesections B com'poset of the vertical arms a and lateral arms 1), i1combination with the hollow cylinder Aam stove-pipe O with its slottedends d, all con structed and arranged substantially as de scribed, forthe purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this14th day 0' October, 1873.
